Abstract
The invention relates to a spinning frame motor-type spindle manufacturing method for reducing friction based on magnetic levitation. The principle of the method includes the step that homopolar magnet rings are installed at the positions where a rotor corresponds to a spindle blade holder or a motor end cover so that the rotor, the spindle blade holder and the motor end cover cannot make axial contact with one another due to homopolar repulsion. Therefore, a series of problems caused by sliding friction in the running process of the motor are avoided.
